An understanding of generational shifts in tourist behavior facilitates the effective prediction and accommodation of future tourism trends. Such predictions are important if the Asia-Pacific region is to reach its tourism potential. This study investigates the domestic travel motivations of 632 Australian Baby Boomer, Generation X, and Generation Y travelers to uncover each generational cohort's travel mindset. Specifically, it considers how the sociohistorical environment when its members "came of age" during adolescence (i.e., thus creating a generation), create a unique lifelong perspective that influences both current and future tourist behavior. Although the survey results show that the travel decision-making process is similar across cohorts, model comparisons reveal generational differences. This study advances the theoretical understanding of the implications of generational perspectives on future travel behavior and provides foresight into demand factors that will drive future travel growth in the Asia-Pacific region and particularly growth in domestic leisure travel by Australians.
